Proteome - CSH

1. What is proteome?

Proteome is the entire set of proteins expressed by a genome, cell, tissue, or organism at a certain time.

Proteomics use mass spectrometry not like genomics and transcriptomics which use microarry. It is because protein can not amplify like PCR.

2. Relationship between genomics, transcriptomics, and proteomics.

Genome contain whole set of gene and DNA between genes. Transcriptome contains every set of spliced mRNA (cDNA). Proteome is final stage, it contains whole set of protein cell have.
So the range become narrower and narrower ,however, related.
